Fascinating Fact:

The marathon race distance of 42.195 kilometres was fixed in 1908 to match the route from Windsor Castle to London’s Olympic Stadium.

In KS3 Maths, measuring length means choosing sensible units, reading scales carefully, and converting between mm, cm, m, and km. You will estimate, measure straight or curved lengths, and apply results to perimeters and journeys.

Key Terms

Length: The measurement of how long something is from end to end.
Millimetre / Centimetre / Metre / Kilometre: Standard metric units for length (10 mm = 1 cm, 100 cm = 1 m, 1,000 m = 1 km).
Scale interval: The value between marks on a ruler or tape measure, for example each small division equals 1 mm.

Frequently Asked Questions (Click to see answers)

How do I read a ruler to the nearest millimetre?

Place the object’s edge at zero, keep the ruler flat, and read the mark level with your eye. Count each small division as 1 mm for an accurate reading.

How do I convert between mm, cm, m, and km?

Use powers of ten: mm → cm ÷ 10, cm → m ÷ 100, m → km ÷ 1,000. Reverse to go larger to smaller (multiply): m × 100 = cm.

How can I measure a curved line accurately?

Lay a string along the curve, mark its length, then straighten the string against a ruler to read the total. Repeat to check your result.
